CONDENSER.

Application fi led December 17, 1927. Serial No. 24.0,e17.

This invention relates to a condenser designed primarily as part of a household refrigerating apparatus, one of the objects being to provide a simple and elficient condenser of the coil type having means whereby the superposed coils can be maintained in proper relation to each other without requiring expensive connecting means or providing a structure likely to get out of order.

Another object is to provide a condenser assembly which does not become disarranged by variations in temperature, is very com act, and can be put together readily.

With the foregoing and other objects in view which will appear as the, description proceeds, the invention. resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings, the preiferred form of the invention has been shown.

In said drawings, 7

Figure 1 is a view partly in elevation and partly in section of the complete condenser.

Figure 2 is a top plan view thereof.

Figure 3 is an elevation showing one end portion of the condenser coil, the adjacent parts for holding the convolutions properly assembled being shown in section on the line 33, Figure 2. I

Referring to the figures by characters of reference 1 designates a tube, preferably of copper bent to form a coil having superposed convolutions indicated at 2 and-3. The convolutions are preferably elongated and the ends and one side of the convolutions are disposed in parallel planes. Furthermore the parallel sides of the convolutions are disposed in staggered relation, the convolutions 2 being extended outwardly fromthe coil beyond the convolutions 3. The opposite sides of the convolutions, however, are crossed as shownrparticularly in Figure 2, each convolution 2 at this side being inclined upwardly and outwardly to merge into the next adjoining convolution thereabove at one end of the coil while each convolution 3 is inclined upwardly and outwardly to merge into the next adjoining convolution 2 at the other end thereof.

The coil 1 is supported by a base 4: and

straddling the convolutions at each end of the coil are elongated U-shaped holders 5 supported by the uppermostconvolutions and having their free ends loosely mounted within spaced apertures 6 formed in the base 4;.

A bar 6 is extended longitudinally of the top portion of the coil and is provided at each end with a saddle 7 designed to rest upon the crown portion of the adjacent holder 5. Each saddle is bowed transversely so as to fit snugly upon said crown portion. Adacent each 01 the saddles is provided a downwardly ofiiset portion 8 adapted to be engaged by a tie rod 9 one end of Which is extended through the base l where it is held by a nut 10 or the like. The lowermost con volution of the coil merges intoan upward ly extended end portion 11 which is arranged within the coil and extended to a nipple 12 which is secured in the center portion of the bar 6, a suitable coupling 13 being provided for attaching the endof the coil to this nipple. The other end of the tube which is extended from the upper convolutionof the coil is preferably bent outwardlyas indicated at 1 1 and has a coupling 15 whereby it may be attached to the adjacent part of the refrigerating unit.

It will be noted that byarranging the holders 5 astride opposed portions of the elongated coil, said portions can be held proper- 1y assembled in alinement as shown particularly in Figure 1 and, as the ends of the holders are mounted freely within the openings 6, said holders will not interfere with expansion or contraction of the coil due to changes in temperature The bar 6 with its saddles 7 constitutes efiicient means for holding the. convolutions properly clamped together where engaged by the holders and also provides a rigid support for one of the ends of the tube forming the coil. It also holds firmly the upper convolution from which the other end of the tube extends. Consequently there is no danger of the coil becoming disarranged because all of the parts thereof will be held firmly under all conditions.

Itwill be noted that, as the convolutions are out of alinement except at certain spaced points, the action of the condenser will be rendered more efficient than would otherwise be possible. It will also be noted that the tying rods 9 are located inside of the coil so that itthusbecomes possible to reduce to the minimum the maximum dimensions of the condenser. V. f
